I've reviewed the Android official document on screen sizes like the reference below: Now I am interested in publishing an application to marketplace and I want to know 1) What I need to support for acceptance 2) What will provide me with good coverage for majority of devices. I don't have time to make sprites and background images for every HW scenario so I r need to know what is common practice. Especially for sprites 32x32 and 64x64? what about density?
